I fallowed everyones advice and added more light, @ more A360w tuna blues. The tank is 8 feet long but only 22" deep and the coral seemed to be doing ok for 2 months but now at full intensity very bright, at night I have the color full blue, first question should it be blue all day? also took your'e advice added more flow 1 more Maxspect Gyre XF150 and the pump is the big hammerhead. next question Tonys tank of the month he writes about additives? I have been using Kalkwasser , been getting coral from blue zoo aquatics they sell good size pieces for about $60 each they say 3"to 4" and they are nice staghorn green the best so far, hydnophora is good color but aggressive maybe that was a bad choice, going to try acropora color tip next 3 pieces where does everyone get there coral? I got a brown acropora cheap 3 months ago its color is getting better sort of
